A lunar model with a spherical surface on which the topography and patterns of the lunar surface are written or carved. Until 1959, when the Soviet lunar probe Luna 3 took pictures of the far side of the moon, humans were only able to see half of the moon, and lunar globes could only be made of half of it. The activities of five American lunar probes, the Lunar Orbiters, between 1966 and 1978 brought detailed close-up photographs of almost the entire surface of the moon to Earth, making it possible to create precise lunar globes of the entire surface. Unlike terrestrial globes, lunar globes are not supported by a special axis. They are usually made by pasting paper with lunar topography printed on it onto a sphere, but the one at the National Museum of Nature and Science in Ueno, Tokyo, is made by carving the surface of gypsum.

球体面の上に、月面と同様な地形や模様を書き入れたり彫刻したりした月の模型。1959年にソ連の月探査機ルナ3号によって月の裏側の写真が撮影されるまでは、人類は月の半面しか見ることができなかったので、月球儀は半面のみしかつくることができなかった。1966~1978年の5個のアメリカの月探査機ルナ・オービタの活動によって、月のほぼ全面の詳細な近接写真が地球上にもたらされ、月全面についての精密な月球儀の作製が可能となった。月球儀は地球儀と異なり、特別な軸によって支えられることはない。普通、球体に月面地形を印刷した紙を貼(は)り付けて製作するが、東京・上野の国立科学博物館にあるものは石膏(せっこう)の表面を彫刻してつくったものである。 [関口直甫] [参照項目] |出典 小学館 日本大百科全書(ニッポニカ)日本大百科全書(ニッポニカ)について 情報 | 凡例 |
